Repair process after water damage
So I am a noob in repair so i need some help.
I have two iphone 6 from my family i will be happy to fix them.
They fell in swimming-pool so they did not stay more than 45 sec or 1 min in water.
(I do not know exactly it is a long time ago like 6 months)
I will begin to fix which fell in W.C.
So the process to fix:
1)Dissassembly and look for corrosion
2)After put them (but which parts?) in alcohol 90%
3)Let it 3-5 hours to dry it
5)Try to turn on
6)If it is not turning on,try to a new battery and lightning connector and maybe screen (which is the best order to replace?)
7)If nothing helps so it is the motherboard so it is dead?
I add some pictures because I do not see corrosion so I do not know which part first to replace because the corrosion...
So I put here the process if someone can tell me advices I am a noob.
And also the 3 questions I have I will be happy to receive advices.
Thanks in advance.
Is this a good question?
